FileDialog -> AccessDenied Exception will crash

[NinthDesertDude]

Tried navigating to D:/DeliveryOptimization on my computer and that gave me an access denied exception that wasn't caught. It would be better if it produced a little dialog for the user whenever any exception occurs and return to the previous or parent directory (if necessary) instead of crashing, since a try-catch block from my end will still result in the user losing their place in the dialog even if I reopen it.
